Overview
SSE allows servers to push data to web pages over HTTP. It is a standard way to stream data from a server to a client, designed for scenarios where the client only needs to receive updates, not send them back over the same connection.
Key Features
- Unidirectional: Data flows only from server to client.
- Automatic Reconnection: Browsers automatically try to reconnect if the connection is lost.
- Standard HTTP: Works over standard HTTP/HTTPS, making it easier to pass through firewalls.
- Text-Based: Primarily designed for sending text data (often JSON).
Use Cases
- Live news feeds.
- Social media notifications.
- Real-time dashboards where the client doesn't need to send data back.
